B(OH)3 + NaOH NaBO2 + Na[B(OH)4] +H2O
How can this reaction is made to proceed in forward direction?
(a) addition of cis 1,2 diol
(b) addition of borax
(c) addition of trans 1,2 diol
(d) addition of Na2HPO4
(a) H3BO3 acts as weak monobasic Lewis acid.
(i) B(OH)3 + NaOH Na[B(OH)4]
on addition of cis 1,2 diol in H3bo3 solution, acidic strength of H3BO3 increases due to chelation effect.
